JSON Schema Validator

Validate JSON against a schema.

  • đź”’ No data stored or uploaded

Click Convert when ready

Override only when Auto cannot parse your paste. Changing this loads a matching sample into Input — click Convert to run. Use Load sample to cycle every format example.

All conversions

Read-only representations of the same 16 bytes. Every textual form is listed here, not in “Prefer format”.

Paste two values: if both sides are valid JSON, a structural diff appears; otherwise UUID / bytes are compared when both decode to the same format.

A
B

Create or edit JSON here (syntax colors), then format, validate, or convert - same as MongoDB $binary UUID blobs on the Convert tab once detected.

New document

Hash, HMAC, AES-GCM/CBC + RSA-OAEP, codecs, JWT decoding, UUID v4, and secure random - all client-side. JWTs use Base64URL (three segments), not a single MIME Base64 block - use Decode JWT below, not raw Base64 decode.

Examples

  • Instance 
    {"name":"Ada","age":30}
  • Schema 
    {"type":"object","required":["name"],"properties":{"name":{"type":"string"},"age":{"type":"number"}}}

About JSON Schema Validator

A JSON document can be syntactically perfect and still violate every business rule your API cares about - wrong types, missing required fields, values out of range. That's what JSON Schema is for, and what plain JSON validation can't catch.

Paste an instance and a Draft-07-style schema and validate them against each other using Ajv, loaded and run entirely in your browser - both stay local, nothing is uploaded.
